Great work here ! The idea is really good and got me hooked. I had some trouble at first to get the actions at the right timing and the difficulty ramps up quickly when you had more actions and the possibility to modify the bpm. But it really is satisfying to hear the little beat while your character is completing the level. Also the fact that there is multiple ways to solve the puzzles is a good thing, to let the players be creative.
I had kind of a similar idea, it's nice to see a sideview version of it.
Impressive that you did this in only 24 hours !
